WPF ListView grouping by 2 columns but display only 1 group header -


a listview displays collection of following class:

public class employee {     private string _department;     private string _manager;     private string _name;     private string _address;      public string department     {         { return _department; }     }     public string manager     {         { return _manager; }     }     public string name     {         { return _name; }     }     public string address     {         { return _address; }     } }

there 1-to-1 relation between department , manager, 2 rows same department have same manager.

i want group department/manager, group header showing "department (manager)".

my collectionviewsource looks like

    <collectionviewsource x:key="cvsemployees" source="{binding employees}">         <collectionviewsource.groupdescriptions>             <propertygroupdescription propertyname="department" />             <propertygroupdescription propertyname="manager" />         </collectionviewsource.groupdescriptions>     </collectionviewsource>

the plan not display first level header (department) , somehow bind both department (1st level) , manager (2nd level) 2nd level header.

3 questions:

  1. to avoid displaying 1st level header, have empty data template in groupstyle:

    <groupstyle>     <groupstyle.headertemplate>        <datatemplate>        </datatemplate>     </groupstyle.headertemplate> </groupstyle>

    this seems clunky. there more elegant way skip group header?

  2. how bind 1st grouping level property (department) 2nd level header (manager) achieve required "department (manager)" ?

  3. is there better way creating 2 grouping level?

thanks

solved main stumbling block, question 2 above: how bind group header property not grouping property.

the solution change data context to:{binding items}. itemsource properties available

<groupstyle>     <groupstyle.headertemplate>         <datatemplate>             <stackpanel orientation="horizontal" margin="0,10,0,3" datacontext="{binding items}" >                 <textblock text="{binding path=department}" fontweight="bold" margin="3"/>                 <textblock text="{binding path=manager, stringformat='({0})'}" margin="3"/>             </stackpanel>         </datatemplate>     </groupstyle.headertemplate> </groupstyle>

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
